When Sony launched the WF-1000XM3 earbuds with ANC they immediately grew to become one of many highest-rated true wi-fi buds in the marketplace.

The one draw back was how massive each the buds and case had been, and the way that result in a lower than best slot in your ears.

Luckily, Sony not too long ago launched its WF-1000XM4 earbuds to deal with these points, and in what isn’t any shock, they’re a implausible improve in each approach.


The “largest” distinction Sony made with the design of its flagship true wi-fi buds this time round was shrinking the case and earbuds. The WF-1000XM4 can now comfortably slot in your pocket and your ears, which was the commonest criticism of the earlier technology.

Sony additionally modified the ear suggestions this time round, going for a squishy foam just like what you’d discover on earplugs. This is smart, as a result of in the event you’re making an attempt to dam out sound, what’s higher than foam earplugs?

Sadly, I’ve smaller than common ear canals and I discovered these new tricks to be too massive for my ears. It was tough for me to get a snug match, even when utilizing the smallest ear suggestions within the bundle. Finally, I swapped the information out for some smaller silicone suggestions I’ve. Should you’re in the identical boat as me, then you should buy one thing like this from Amazon and substitute the information for a extra comfy match.
